          Summary

          Transmissible gastroenteritis virus was administered orally to cats. No clinical disease resulted but infectious virus was isolated from faeces for up to 22 days after infection and serum antibody was detected by neutralisation and immunofluorescence tests.

            Detection of transmissible gastroenteritis virus neutralising antibody in cats

            Summary High titres of neutralising activity to transmissible gastroenteritis virus (TGEV), a porcine coronavirus, were found in sera and peritoneal fluids from cats infected with feline infectious peritonitis (FIP). A small proportion of cats, from a hospital population unaffected by FIP, also had neutralising activity. Procedures to remove non-specific viral inhibitors, including treatment by heat inactivation, trypsin, sulphydryl reagent and kaolin absorption were unsuccessful. The active component was unable to neutralise another porcine coronavirus, haemagglutinating encephalomyelitis virus or the porcine enterovirus, Talfan. Gel filtration of feline sera and peritoneal fluid demonstrated high levels of the neutralising activity in the area corresponding to 7S IgG, which could be removed by absorption with specific anti-IgG serum and these properties are suggested to be consistent with those of antibody. These findings imply that there is a coronavirus in cats which is antigenically related to TGEV and its possible nature is discussed.

              Antigenic relationship of the feline infectious peritonitis virus to coronaviruses of other species.

              Utilizing the direct and indirect fluorescent antibody procedure, the antigenic relationship of the feline infectious peritonitis virus (FIPV) to 7 other human and animal coronaviruses was studied. FIPV was found to be closely related to transmissible gastroenteritis virus (TGEV) of swine. Transmissible gastroenteritis virus and FIPV were in turn antigenically related to human coronavirus 229E (HCV-229E) and canine coronavirus (CCV). An interesting finding in the study was that the 8 coronaviruses selected for this study fell into one of two antigenically distinct groups. Viruses in each group were antigenically related to each other to varying degrees, but were antigenically unrelated to coronaviruses of the second group. The first antigenically related group was comprised of mouse hepatitis virus, type 3 (MHV-3), hemeagglutinating encephalomyelitis virus 67N (HEV-67N) of swine, calf diarrhea coronavirus (CDCV), and human coronavirus 0C43 (HCV-OC43). The second antigenically related group was comprised of FIPV, TGEV, HCV-229E and CCV.
